摘要： A noise canceller of this invention includes a pickup antenna arranged in proximity to a noise signal generation source to extract a noise signal generated by the noise signal generation source, and a noise cancellation unit having a first input for receiving a television signal from a television signal receiving antenna and a second input for receiving the noise signal extracted by the pickup antenna. Herein, the noise cancellation unit removes a noise signal fed from the television signal receiving antenna. Thus, the noise canceller prevents degradation in television signal reception sensitivity due to the noise signal generated by the noise signal generation source.

摘要： A single circuit-configured tuner is capable of selectively switching between two operating modes. A radio frequency signal, quadrature-modulated by a base-band digital signal, is captured into a single input terminal and then split into two signals. Each signal is fed into a mixer at each branch circuit block. Each mixer receives an oscillating frequency of a local oscillator. At this time, the oscillating frequency determines the operating mode. In the first operating mode, as the oscillating frequency is determined to be equal to the rf signal, the rf signal undergoes quadrature detection, resulting in that the original base-band digital signal is obtained at an output terminal coupled to each mixer, that is, the tuner works as an I/Q detection tuner. On the other hand, in the second operating mode, as the oscillating frequency is determined so that the difference between the oscillating frequency and the frequency of the rf signal is to be equal to an IF, the tuner works as an IF tuner.

摘要： A vibration control device 1 in accordance with the present invention is provided with a liquid lever mechanism 4 which has an action member 5, a liquid chamber 6 and a driving plate 7, and is used for enlarging a displacement, a piezo-actuator 2 which can be displaced in a direction so as to change the volume of the liquid chamber 6, and a rubber vibration isolator 3 which is placed between the liquid lever mechanism 4 and the piezo-actuator 2 in series therewith. This vibration control device 1 has a low natural frequency so that it has a superior passive vibration-blocking performance at high-frequency bands, while maintaining a superior active vibration-blocking performance at low-frequency bands, and also makes it possible to achieve a small size.

摘要： A radio-frequency signal receiver and its manufacturing method are disclosed. A tuner receives a radio-frequency signal, and a demodulator receives an output signal from the tuner. An error corrector receives an output from the demodulator. A determiner determines whether or not an error rate supplied from the error corrector is not less than a predetermined rate. A controller receives an output from the determiner, and based on the determination, the controller controls a plurality of sections forming the radio-frequency signal receiver. The controller controls selectively one of the plurality of sections, thereby lowering the error rate. A manufacturing method of this receiver makes a memory, coupled to the controller, store a shift-amount of frequency corresponding to an interference signal in a pass-band of a narrow-band filter.
